Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005600, here are decompositions:

7 + 1005593 = 1005600
19 + 1005581 = 1005600
47 + 1005553 = 1005600
59 + 1005541 = 1005600
73 + 1005527 = 1005600
97 + 1005503 = 1005600
107 + 1005493 = 1005600
163 + 1005437 = 1005600

Showing the first eight; more decompositions exist.
